Ginevra Blackwood

Ah yeah, reading that source I can't see it working on charming except as an NPC event. I have been reading this under notable creatures tab and it is a significantly less terrifying entity, at worst coming out and clawing someone's face for hurting the host. What you linked is much more consistent with what Fortitude Greengrass described. So I will keep her as a simply bad witch with a lot of internalised distress rather than a monster that might cause existential problems for half the characters on the board.

Thanks both
